| 摘要: |
| 提出了基于动态理想解法（TOPSIS）的调制识别方法，将各特征参数看成一个整体，对各个调制方式判别打分，根据得分高低来判定调制样式。该方法简单、方便，弥补了传统判决树法判决门限难于选取的缺点，同时克服了神经网络法训练时间长、对算法要求高的难题。仿真验证了所提方法的有效性，在信噪比10 dB以上时正确识别率接近100%。 |

| Abstract: |
| A modulation classification method based on the dynamic Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) is proposed.Each characteristic parameter is regarded as a whole,and each modulation mode is distinguished and marked.Finally the modulation mode is determined according to their scores.This method is simple and convenient,which makes up the shortcoming of traditional decision tree method that it is difficult to choose the decision threshold.What’s more,it avoids the long training time of neural network method,as well as high algorithm requirements.The feasibility of proposed method is verified by simulation experiments.The correct classification rate of modulation mode approximates 100% when the signal-to-noise ratio(SNR) exceeds 10dB. |
